I was wondering if I should set up another personal bank account for all activities.

I am looking to borrow 50k from equity in a 4 unit investment property to use as a downpayment on a personal residence. 

I'm personal friends with the owner and they do a great job. https://www.livindy.co/ 

I would be happy to refer you to the right person if you are interested, just let me know!

. $80k will net you $1200/mo.That said I am of the opinion that rent rates (up significantly since Covid) are plateauing, I don't expect to see them climb significantly higher.Regardless, factor my position of being a cash-in-hand personality who doesn't much care if the hype is telling us to buy-buy-buy or run for the hills.

Nowadays I use what I've learned and help investors building their rental portfolios in class C neighborhood while personally I either build Padsplit in class C or build high end vacation rental in class A area and hold them. 

Personally, we're okay with properties that cashflow decently, but have long term appreciation upside too.

I haven't personally gone myself, but plan to soon.

I start with a conversation with the person to understand what they're looking for and whether or not my property is a good fit for them.

i want to keep the group small. not like industry scale crowdfunding.if I can find a property which has okay cashflow (which is hard anyways). and can collect around 10/20 people who wants to invest some cash each.I build a company to own the property and give each person a share. and give yearly dividend to each, until sold.
